Supplying Power To Camera

only if the vd is too much on the existing cable lol, then your choice is made!

True.

I'll fit a mounting box for the camera that will give enough space.

seems to me why not just use 'shotgun' cable? (for the o/p this is RG59 with a 3 amp twin cable moulded to it.

it will work easily over that distance with minimal volt drop, and easier/cheaper than cat5e + converters.

Shotgun cable is 2 cables joined along its length. It can be 2 co-axes (RG6, 59, CT100, CT125 etc...), a co-ax and 2 core, or a co-ax and multicore.

Not so sure arf, depends where you get your cable from and how good you are with a BNC crimp plug.

[whistle]

Chep Shot gun and BNC's dont mix

LOL when you stip the 2 core's back it leaves a small amount of sleave on the coax side its a PITA to get the BNC to fit, you end up with a knife cutting buts off.

?

i've never had a problem with it, i use the same bnc's i always do supplied by Gardiners in packs.

if i had a problem i would simply just take off the moulding with a bit of sand/glass paper or a b@stard file, is anyone really saying it's more difficult to terminate than crimping a RJ45 plug in each end of a CAT5e for the O/P?

hi Lurch,

i'm trying to keep my Post short - thanks for the dictionary of terms so exsplained for the o/p, but i termed in relation to CCTv (relevance - i just like it )

Gardiner's supply my cable and BNC's, come's in white or black, given the twin cable 'mass' it has more copper in it than Cat5e, even if paired up (so less chance of voltage drop), and has a bit more seperation from the video side than CAT5e.

if he decides to pump ac to the camera and regulate to 12 volts at the head, then imho this is a factor in favour of the shotgun cable, but hey we all have our own idea's, many alternatives to solving problems - thats why we joined a forum.

Probably my fault by starting with a power question & getting led into using cat5 for video. Well I'm learning interesting stuff anyway.

As for fitting the voltage converter at the camera end - that's a good point. Only problem for me is that it's being fitted on the outside of a double brick wall so it would be difficult to conceal the wires plus the converter. Would it be worth the effort you think?

hi basilb,

i think you mis-understand, you don't have to fit the ballun (or the voltage reg if used) right next to the camera, so if there is a convenient loft run Cat5e cable to this point just run ordinary cables from inside to out (placing all the gubbins in the loft).

If you send AC up the Cat5 and try to regulate it at the camera end with a voltage regulator, the balun

Shotgun would be the easiest & cheapest & there should be no problem for only 40 metres.
